MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202641007473 A) filed by Vellore Institute Of Technology, Vellore, Tamil Nadu, on Jan. 26, for 'a system and method for preventing unauthorized recording using infrared grid-based detection.'
Inventor(s) include Dr. Subramaniyaswamy V; and Abhijai S.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a system and method for preventing unauthorized recording of displayed digital content. The system comprises an infrared grid sensor (105) configured to passively sense thermal radiation within a field of view (114) in front of a display, and a micro-controller (108) operatively coupled to the infrared grid sensor (105). The micro-controller (108) processes thermal data to detect a warm lens detection condition (115) corresponding to a recording device aimed at the display. Upon detection, the micro-controller (108) generates a hardware-level HID 'panic' signal (116) transmitted through a USB connector (111) to a host device, causing masking, locking, or suppression of the displayed content. The system operates without capturing visual images and provides real-time, privacy-preserving protection against unauthorized recording using a hardware-enforced response mechanism."
